This listing contains a Copper Age DC Comics.  It is from the Detective Comics series and is the key issue #612.  I bought this comic in 1990 already bagged and boarded in April of 1990 at a card show in the Anaheim Convention Center.  This comic has been in a truck unopened for over 30 years.  I am now 75 and selling my comics.  I have graded this comic as NM+ in my opinion and as I believe the scans show because it has never even been opened before the scans today.  The pages are WHITE.  A great buy for a great copper age beauty at a reasonable price.
